unlessn't
I'm sorry, I hate the "unless" so much
At one of my first jobs, I was tasked to rewrite a bunch of legacy Perl scripts in Python and the unless lines always made me trip up. I don't know why but it really messed with my mental flow when reading Perl code
Basic used "else".
It's nice. "if", "then", and "else". I spent a year programming a shitty roulette game on an Apple 2e back in high school. I still remember the joy of using if/then/else paired with goto to make a horrible mess of spaghetti logic.
But yeah, "else" is nice.
Using a standalone 'else' would tickle my brain in the same nice way that being able to declare a variable inside an 'if' statement as if it were a 'for' loop (which you can do in modern C++) does.
Many languages let you scope variables.
In c# you can create an arbitrary scope to declare variables in. Most likely in others as well.
Ah clever, didn't think of doing this. Not having to encapsulate if statements in scopes would still look cleaner though
It's handy if you're creating temp variables for single use that you don't need to use again.
Although I admit I've only ever done it a couple times lol
Again in c# you can omit the scope and only the next statement is part of an if or loop.
Or a rust "if let"
Ooh yes. Rust is king when it comes to this sort of inline stuff. Inline
match. Mmmmmm!Block scoped variables are bad?
🤷♂️
Let's just scrap every language except various forms of BASIC.
Please God, no. I had to unravel terminal scripting code that was written in some propriety BASIC language with basically no documentation.
Took me a chunk of time trying to figure out how it worked before I made the realization that it was BASIC
Try PL/SQL.
I haven't written any Ruby for years, but I still praise it in every conversation I have regarding programming languages. It's basically a much simpler Python, with some design ideas that are both beautiful and deeply strange.
Ruby was designed to evoke joy and they absolutely succeeded. Usually, programming is mostly a means to an end to me. But using Ruby just feels so amazing, it's almost impossible to even describe to somebody who has never used it before.
The Perl version of it is even greater!
